Dec. 30, 1952 Filed o ct. a. 194s Patented Dec. 30, 1952 CARD REPRODUCING MACHINE Knut Andreas Knutsen, Paris, France; vested in the Attorney General of the United States Application October 8, 1948, Serial No. 53,503 In France May 13, 1941 The invention relates to a punching machine for the transfer of perforations from one or a plurality of sequentially fed perforated record cards to one or a plurality of other sequentially fed record cards, under the control of the former cards.

One object of the invention is a punching machine provided with a data receiving device for the reception from a card of a plurality of items, for each column of the card to be perforated, and a punching device for the punching, in a single operation, of all items transferred to said data receiving device. y

Another object of the invention is a punching machine provided with two card feeding devices, which together are provided with one or a plurality of analyzing devices for transferring items from one or more sequentially fed cards to the data receiving, or storing, device of the punching machine during the feeding of the cards, and for punching in a blank card perforations corresponding to the transferred items.

Further objects of the present invention will be seen from the following description which shows one particular form of embodiment of the invention,` and some of the different ways of utilization of the machine.

6 Claims. (Cl. 164-115) Figs. 12, 13 and 14 are graphs showing the movements of the cards in the machine.

Figs. 15 and 15a taken together (and. juxtaposed along the dash-dot lines at the top of Fig. 15a and at the bottom of Fig. 15) form a wiring diagram of the electric circuit connections of the machine.

Figs. 15b and 15e show modiiications of the plug connections of the wiring diagram Fig. 15 to punch cards in series by a master card and to punch a card under control of several cards respectively.

For the sake of ensuring comprehension of the drawings, some details have been omitted or only partially represented.

Fig. 1 shows a schematic plan View of the machine `with the two card feeding devices. The cards are analyzed during their movement by brushes which establish an electric circuit through each perforation of the card.

The card feeding device shown to the left in Fig. 1, a section of which is shown in Figs. 3 and 3a, will be hereinafter designated: Blank card feeding device; in said feeding device the cards are moved from hopper I5 to hopper` Iii past the following parts: a pair of rollers ll-i, a row of analyzing brushes BSP, the pairs of rollers i920 and 2l-22, punching device 23 with a pair of rollers I28-I 29 (see also Fig. 5), the pairs of rollers 25-21 and 28-29, a row of analyzing brushes BCP and a pair of rollers Sii-3l. Above the punching device is the data receiving device 32, in which the items to be punched are stored.

The card feeding device shown to the right in Fig. 1, a section of which is shown in Figs. 4

' and 4d., will be hereinafter designated: Pattern card feeding device; in said feeding device the 'cards are moved from hopper 34 to hopper 35,

past the following parts: a pair of rollers 31-38, a rowof analyzing brushes BSMthe pairs of rollers 3.9-40 and lil-42, a row of analyzing brushes BLM,` the pairs of rollers43-44 -45-46 and 41-48, a row `of analyzing brushes BCMand a pair of rollers 49-50. In the pattern card feeding device, cards are generally run throughv the machine without stopping. In vthe blank card feeding device, eachcard is'stoppedduringythe brushes BCP and BCM.

However, due to a disconnection of the two first rollers I7 and I8 from the driving shaft, 'under the control of magnet 81, Fig. 2, the blank card may be arrested before its passing the analyzing brushes BSP, while the pattern card continues to be moved forward. The two rows of analyzing brushes BCM and BLM are at such a distance one from the other that index point positions of the same value, for example the value nine, in two successive cards, are simultaneously analyzed by the corresponding rows of Said analyzing brushes.

Different utilizations of the machine will be hereinafter described.

(l) Duplication of cards-The cards which are to be duplicated are stacked in the patt rn card hopper and analyzed one by one by the corresponding analyzing brushes. Gwing to said analysis, the items corresponding tc the .perfo- .rations of the pattern cards will be entered into the data receiving device, whereupon the corresponding perforations will be perforated in the blank cards which are moved in the blank card feeding device. A card which has just been punched, will be compared with the corresponding pattern card by simultaneous analysis of said cards. In addition to items transferred by the analysis of each pattern card, the data `receiving device may contain invariable items which have been entered either manually or from a counter and which items will be punched in each blank card.

(2) Brmching of cards in series-Jn the -blank card hopper are stacked pattern cards 'each followed by any desired number of blank cards. Each pattern card will cause vthe resetting to zero of the data receiving device, owingto the .analysis of the pattern card by a row of brushes located before the punching device, and will thus be moved 'past the punching device without being punched. 'Owing to the analysis of the pattern card by another row of brushes located behind the punching device, the items corresponding to the perforations of the pattern card are en- .tered into the data receiving device, and the following blank 'card is punched correspondingly .during the subsequent punching operation. As the data receiving `device may only be reset to lzero by a pattern card, all the following blank cards will be punched in accordance with the first blank card after it has been punched according to its preceding pattern card.

`(3) .Comparison of perforated-cards 'in scrz'cs.-

The cards 'which Vhave been punched during the punching operation referred to in point 2 above may, without interrupting said punching in se ries, be stacked vin the pattern card hopper, and movedby this feeding device in order to `be compared, by Asimultaneous analysis lof two .con-

secutive cards, by two rows of analyzing brushes.

(4) 'Punching of cards under simultaneous control of severa-Z other cards-In the pattern card hopper Vare stacked .master cards, cach followed -byjany desired number fof pattern cards. Blank cards are stacked'in the blank card hopper and moved, simultaneously with the pattern cards. The items corresponding to the perforations of the master cards will Abe transferred, under the control of analyzing brushes, to determined columns of the data receiving device, while the first blank card is arrested. Then, the items corresponding to the perforations of the Lfirst pattern card, will be transferred, under the control of said analyzing brushes, to other `columns of the data receiving device, and the first blank card will be simultaneously advanced. By the subsequent punching operation, the items from the first master card, and the items from the rst pattern card will be punched in the first blank card. Then the data receiving device will be automatically reset to zero only for the columns containing items from the pattern card, whereas items from the master card and invariable items entered from the counter, remain inthe data receiving device. By the analysis of a second pattern card during the next cycle of the machine, data will be transferred from this card to the data receiving device. By the subsequent punching operation, data from the lsecond pattern card and from the master card lor the counter) will be punched in a second flank card and so on.

The first blank card thus punched, will be analyzed by the last row of analyzing brushes of the blank card feeding device, simultaneously with the yanalysis of the first pattern card by the last row of analyzing brushes of the pattern card feeding device, in order to compare the two cards.

lPig. 2 is a plan View showing the gear drive for the lower feed rollers of the two card feeding devices, together with the actuating mechanism for the two pickers, for the punching device, for the vdcta receiving device, for the cam shafts,

Each feeding device comprises two sideplates i3-i4 and i5-55 fixed to the table 5?, l 3, and supporting the lower feed rollers. To each lower roller, for example .2 I, Fig. 3, corresponds an upper roller, for example 22. Each upper roller is driven by the lower roller bymeans of toothed wheels. i

Each row of brushes is composed oi ludivid ual brushes which make contact through the perferations 'of the cards, with a Contact roller Figs. 3 and 3a, and lill, SL62, Figs. 4 .and 4c. Said brushes are Vinsulated one frein another and connected to a plug contact.

The machine is driven by a motor, placed under the table, by means of a belt which Vdrives a pulley t5, Figs. 2 and 7. The pulley drives through shaft si and'wheels S5, te, a shaf., which, by a V'clutch -53 of conventional type controlled by a magnet Q3, drives shaft "it On the latter are fixed two toothed wheels ii, 'i2 feach of which drives a wheel i3, 'it fixed on shaft "i5, Figs. 2 and Further, shaft 'i9 drives through bevelwheels l, l?, shaft 'it which, through wheels is and til drives the longitudinal shaft tI situated between the two card feeding devices. Shaft iii drives through worm-wheels 82, t3, the lower roller it of the blank card feeding device. This roller has on the Aright, Fig.'2, an 'extension which constitutes the feed roller 3s, Figs. 2 and 4, of the pattern card feeding device. Roller It drives, through gears S, i355 and clutch A88 controlled by magnet 8i, the shaft s@ which, through wheels si, 32, drives the contactroller 58 which, through wheels 92, 9e, drives the feed roller I'. On wheel 93 is adjusted an eccentric `pivot 95 which, through connecting rod Sit., imparts a reciprocating motion to picker shaft il?. On roller ,39 is fixed toothed wheel .HIM which, `through 'gears Ing, ies, drives the feedrollerdl, Figs. Zand 4, and .through/gears IM, H35, ldrives the Contact relier tu. The feed roller 3? is driven by wheels It, Ist, lill. Wheel lill is provided with an eccentric pivot I which, through connecting rod |39, imparts a reciprocating motion to picker shaft IIIl.

The longitudinal shaft 8l drives, through worm-wheels 'I I3, IIA the feed roller '2i which, through wheels I I5, IIB drives shaft I Il. On the latter are fixed a cam I I8 and a toothed wheel YI I9 provided with teeth only on a determined portion of its periphery. Wheel ||9 meshes with wheel fixed with a cam |2| on shaft |22. Shaft |22 drives through gears |23, |24, |25, |26a, the shaft |21 of feed rollers |28, |29. These rollers are not shown in Figs. 2 and 3 but are situated on a, vertical line through shaft 15, and are Vshown in Fig. 5. On roller |28 is fixed a toothed wheel |26. Toothed wheels |26, |26a drive each an upper feed roller |32, |33, Fig. 5, through toothed wheels |30, I3 I. Said rollers move the card through the punching device and hold the card motionless on the die plate during the punching operation. Therefore, these rollers are driven intermittently; this is obtained by the suppression of certain teeth on Wheel I I9, Fig. 2. At the time when wheel I |9 is not coacting with wheel |20, cam |I8 engages (see Fig. 6b) a lug or tooth of cam |2| and stops the latter andthus the shaft |22 and the shaft |21 of the rollers. Shaft ||1 makes one revolution for each cycle of the machine, and timing is so coordinated with the driving of the cards, that one cycle corresponds to eighteen time intervals between two index point positions of a column of the card. The time during which shaft `|21 is at rest corresponds to three of said time intervals. Further, the longitudinal shaft 8| drives through worm-wheels |40, |4|, feed roller 26, Figs. 2 and 3a, and feed roller 45, Figs. 2 and 4a. Roller 26 drives, through wheels |42, |43, |44, feed roller 28. Feed roller drives feed roller 43, through gears |46, |41, |48, and contact roller 6| through gears |49, |50. Shaft 8| drives through wheels |53, |54, the shaft which actuates an impulse emitter |56.

Further, shaft 8| drives, through wheels |58, |59, the contact roller 59 which, through gears I6I to |64, drives the last feed roller 30 of the blank card feeding device. Shaft 8| drives, through gears |66, |61, the feed roller 49 which. through gears |68 to |10, drives the Contact roller 62, and through gears |1|, |12, the feed roller 41. Roller 49 drives further, through gears |14 to |18, the shaft |60, Figs. 2 and 3a, which, through wheels IBI, |82 and |83, |84, drives the cam shafts |65, |86, which extend slantwise upwards, on the two sides of the data receiving device, Figs. 2, 3a and 9. Shaft 9| drives, through gears |90, |9I, the cam shaft |92 which, through gears |93, |94,

drives another cam shaft |95. When the motor is rotating and driving shaft 10 through clutch 69 is rendered effective by energization of magnet 68, all the shafts, feed rollers, cam shafts, etc., which have been referred to hereabove, will be driven, except the contact roller 48, the feed roller I1 and the picker shaft 91 `which will be driven only when the clutch 88 is rendered effective by energization of magnet 81. Shaft 8| performs two revolutions, all the cam shafts one revolution, and the two picker shafts a reciprocating rotative movement for each cycle of the machine.

The feed rollers, except feed rollers |28, |23, Fig. 5, are rotated so as to advance the cards the same distance for each cycle of the machine. Feed rollers |28, |29 have an intermittent movement, in order to hold the blank card motionless in relation to the die plate during the punching operation. The movement of the cards is obvious from the graphs shown in Figs. 12, 13, 14. In thosegraphs, time is indicated in ordinates and is measured in cycles of the machine; the distances covered by the cards are read on the abscissa axis. The movements of the front and of the back of any card represented, for instance CVI, are thus gured by two parallel and generally slanting lines. In those figures are shown side by side the progressions of the cards in both feeds of the machine, that is respectively through the blank card feeding device on the left and through the pattern card feeding device on the right.

At the upper end of Fig. 2 is a shaft |191 which may be actuated by hand by a crank |98 for resetting to zero all the columns of the data receiving device.

The hoppers and pickers are the same for both card feeding devices. Their construction is well known and is illustrated in Fig. 4.

The upper feed rollers are all alike. They are maintained on each side by bushes which are guided in grooves of the upper side plates, and

each upper feed roller is pressed against a lower roller by two springs. Between two pairs of rollers, the card is guided by guide plates, for example 20|, 202, Fig. 3. The contact rollers are connected to the circuit by a brush, for example 203, Fig. 4. In the pattern card feeding device are placed three card contacts CC204, 205, 206; the blank card feeding device comprises two card contacts CC201, C0342 (the latter being shown only in Fig. 15a, but its embodiment being easily imagined by similarity with CC201 shown in both Figures 3 and 15a); these contacts are closed when a card actuates a lever, for example 208, Fig. 3. Two individual brushes 209, Fig. 3, and 2|0, Fig. 4a., are used to stop the machine when there are no cards under the brushes, owing to a deficient feeding of the cards.

The punching device and the data receiving device will be presently described. The shaft 15, Figs. 3 and 5, performs one revolution for each cycle of the machine. Each

wheel

13, 14 is fixed with a cam 2|3, 2|4, on a sleeve 2|5, 2|6, said sleeve itself forming a cam 2|1, 2|8 and being xed to the shaft. The die plate comprises a plate 220 provided with openings for the punches, said plate being riveted on a support plate 222 provided with slots 22|. Each slot corresponds to a horizontal row of perforations of the card. The support plate is screwed to a frame plate 223 which may be actuated vertically in vertical guides of side plates 224, 225. On each side of the frame plate is secured an

axle

226, 221 having a

follower roller

228, 229 which rests on the upper portion of cam 2|3, 2M. The frame plate has on each side a

downward extension

230, 23| to which is secured an

axle

232, 233, having a

follower roller

234, 235, which is pressed against the lower portion of cam 211, 2|8. The cams are so shaped that, when shaft 15 is rotating, a short upward movement is imparted to the frame plate; then a short downward movement is imparted to the same, after which the frame plate remains motionless in its lower position during the remaining part of the revolution of the shaft.

Above the die plate is a lower punch guide which is secured to the frame plate, so as to leave an open space for the passage of the cards. Further, to the frame plate is fixed an upper punch guide. Said punch guides are composed of one or several

perforated plates

231, 238 secured to a

support plate

239, 240 provided with slots. The punches 24| have a notch in which is engaged a bar 242 which holds each punch in its normal position. The bars 202 are at each end xed to the frame of the machine and are stationary. On the upper punch guide is secured a..second series of bars 243 which participate in the movement'of theV die 'plate and serve to restore'the punches totheir normal position after the punching operation. By the upward movement of the die plate, the unperforated card will push the punches upwards. When a latch lever 244 is in its latching position, that is in a, position in which its lower extremity overlies the upper extremity of a corresponding punch 24|, the upward movement ofthe corresponding punch will be prevented and the card will be punched. By the downward movement f the die plate, the bar 242 causes the punch to be withdrawn from the card; this permits the card to be advanced again. Fig. 3a shows one row of punches for one column of the card. From left to right, the punches correspond tothe index points from nine to zero, eleven and twelve. The punching device has eightyv such rows of punches.

Above each punch is placed a latch lever 254. These latch levers are xed on each side of a plate 2155 which is common to two columns of the card, by axles Ztl which traverse the plate. To each latch lever is attached a spring 251 which is fastened at its other end to a three arm lever 248 which is mounted on a pin 2d@ iixed to the plate. |The right hand arm of lever 243 is urged against the upper end of the latch lever by said spring which holds this lever 258m its normal position. The spring urges the latch lever against the right hand arm of lever :8 and thus the latch lever is held in its normal position. The left hand' arm of lever 2M is connected by a pin 250 to a rocking lever 255 pivotally mounted on a rod 252; the left hand end of said rocking lever is just beneath the lower edge of the stop bar 253 when the latter is in its locking position.

Each rod 252 carries twelve rocking levers 25|, and its lower end is provided with an opening in which a pin 254 is engaged. This pin is secured to a lever 255 which is pivotally mounted on plate 255. Lever 255 may be actuated by the resetting bar 255. To the rod 252 is attached a spring 251 which, at its other end, is fixed to the plate and draws the rod to its lower position of rest. At its upper portion, the rod is provided with an opening in which is engaged a pin 258 fixed to the lever 259 which is pivotally mounted on the plate. To lever 259 is connected a link 2590'. which, at its other end, is connected to the armature 255 of magnet 25|. To each column of the card corresponds a magnet 25| which is secured to a plate 262.

The movement of stop bars 253 is governed by a double cam drive mechanism, one drive on each side of the data receiving device. The double drive mechanism serves to avoid torsional strain on the stop bars. The two drive mechanisms being alike, one only will be described.

Each stop bar 253 is at each end riveted to an axle 265, Fig. 8 lodged in a support xed to each side plate 255 of the data receiving device. At the end of each axle is riveted a sleeve 261, to which is iixed a stud 25S which projects from one side ofthe sleeve. Adjacent to each end of the stop bar and cooperating with said stud 255, is one of the twelve cams 21d, Fig. 9, which are secured to the slanting shafts |55, |85 on each side of the data receiving device. Due to the rotation of these shafts, cams 21d strike one after another against a corresponding stud 253 and cause the stop bars to turn about their longitudinal axis, one after another, into locking position. A moment later, the spring 259 restores the stop bar to its initial position. There is a stop bar for each perforation to be made in a column of the card.

In Fig. 3a, from bottom to top, the stop bars correspond to the index points nine to zero, eleven 'and'twelve The cams are so adjusted that the stop bar corresponding to the nine index point is in locking position when the nine index point position is analyzed by one of the analyzing brushes BCP or BLM. The stop bar corresponding to the eight index point is in locking position when the eight index position is analyzed and so on. When any one stop bar is in locking position, all the other stop bars are in their initial position of rest. The cams 212, Figs. 9 and 3a, serve to move the bar 258 once for each index point position of a column of the card which is analyzed, so as to secure that rods 252 are in their initial lower position at the beginning of the analysis of each index point position.

The transfer of an item perforated in a card, to another card is eected as follows: It is assumed that a perforation eight of a column of the card is analyzed by one of the analyzing brushes BLM, and that the brush in question is connected to a magnet 2G The second lowermost stop bar is at this time in locking position, Fig. 3a; all the other bars are in inoperative position. The energization of magnet 26| will cause a leftward movement of the corresponding link 259a and subsequent upward movement of the rod 252 with the twelve rocking levers 25|, as shown in Fig. 3a.. Rocking levers 25| will rock about the pins 256. The second lowermost rocking lever corresponding to the eight index point will strike with its left hand end the corresponding stop bar which is in locking position; therefore the right hand arm of the rocking lever will be moved in opposition to the eiect of spring 241, so that lever 243 may be rocked in a clockwise direction and that the corresponding latch lever 254 may be released. This latch lever will be moved into latching position by spring 241 as shown in Figs. 3 and 3a. When the perforation which is analyzed has passed the analyzing brushes, the energization of the magnet ceases and spring 251 draws rod 252 into its initial position of rest. If the analyzed card has in the same column a second perforation, for example a perforation seven, when this perforation is analyzed the third lowermost stop bar is in locking position, while the secondlowermost stop bar has been restored to its initial position of rest. When the magnet is energized again, the rod 252 is moved upwards again and the third lowermost rocking lever will hit the stop bar which is in locking position, and thus, the latch lever for the seven index point will be drawn into latching position by the corresponding spring 241. When a card has for example twelve perforations in the column which is analyzed, the twelve latch levers 244 will be moved into latching position. A latch lever moved into latching position remains in this position until the card has been completely analyzed and the subsequent punching operation is finished. The latch levers for variable items will then be restored to their initial position by means of a special device which will be presently described.

On each plate 245 are movably secured two

rods

215, 216, Fig. 3a. Each rod is provided with twelve noses 211 projecting laterally, so that each nose may engage a corresponding latch lever. Each rod is provided at each end with an elongated opening in which a stationary guide pin 218 is engaged. To each rod is attached a spring 219 which, at the other end, is fixed to the plate 245 and which draws the rod to the right into its position of rest. In a notch 280 of each rod is engaged the upper arm of a three arm lever 28| which may rock about a stationary pivot 289. Above the left hand arms of all levers 28|, extend two

bars

282, 283, Each bar is provided with 80 openings in each of which a pin 284 may be inserted and held by a strip 285. To each lever 28| correspond for each bar, one opening and one pin. When a bar is moved downwards, each pin will strike against the corresponding lever 28|, which will move the

corresponding rod

215, 216 leftwards and effect the resetting to zero, that is the resetting into their initial position of all latch levers of one column of the data receiving device. When for a bar, selected pins have been previously removed, the resetting to zero of the columns of the data receiving device which correspond to the removed pins, will not 'be effected. The movement of bar 282 is automatically controlled, from the perforated card, by a magnet 281 (see Fig. 10), and the movement of bar 283 by another magnet 288. Therefore, after a punching operation, the latch levers corresponding to any column of the card may be reset to zero, under the control o-f the analyzed card itself.

The bar 282 is at each end secured to a lever 290 which `may rock about a stationary pivot 29| Fig. 10. The bar 283 is at each end secured to a lever 292 which may rock about a stationary pivot 293. One of the levers 292 is connected, by a link 235,` to lever 291. The other lever 292 is connected by a link 299, lever 30| and link 303, to the same lever 291 which may rock about a stationary pivot, Figs. 10 andl ll. The two levers 290 are connected in the same manner to lever 296; only the link 294 corresponding to link 295 is shown. A

spring

304, 365 tends to rock each lever 296, 291, so that the right hand arms, Fig. 1l, of these levers rest against an adjustable stop screw 306, 401. To each lever 296, 291 is pivotally connected a

lever

308, 309, which is provided at its lower end with a nose 3|0.

Lever

308, 369 is further provided with a stud`3|3 which engages the forked extension 3| 4, 3|5 of the armature of

magnet

281, 288. Normally spring 3|1 holds the armature in the position in which nose 3|0 is not beneath lever 3|8. If the magnet is energized, the armature will rock lever 308, 308, so that its nose comes under lever 3|8 in order that, if the latter is moved downwardslever 296, 291 may be rocked clockwise, and bar 282, 283 moved downwards all the while keeping its horizontal position. Lever 3 I 8 may rock about a stationary pivot 3 I9 and is rocked counterclockwise by cam 328 after each punching operation, Fig. l0. A third resetting bar 322, Fig. 3a, when moved to the right, rocks the lower arms of levers 28| and restores thus all the latch levers without exception to their initial position. Bar 322 is moved by hand by rotating a shaft |91 provided with a crank. On this shaft and on each side of the machine is secured a

cam

323, 324, each of which cooperates with a lever 325, 326; each lever is connected, by means of a link 321, 328, to an end of bar 322.

The operation of the machine will be presently described with reference to the circuit diagram, Fig. 15. In the diagrams, all cam contacts are designatediby the letter C followed by the numeral of the contact. All relay contacts are designated by theV numeral of the magnet by which theyare controlled,l followed by a letter. Relay contacts are shown in the positionV which they 10' occupy when the corresponding magnet is not energized.

(1) Duplication of eerder-The plug connections are shown in Fig. 15` by dotted lines. Only two columns of the card are plugged. Brushes for columns one and two of the row of brushes BLM are each connected to a magnet 26| of the data receiving device by plug connections 350. For column one, one of the brushes BCM is connected by a plug connection 35| to a coil of a control relay 451, whereas for the same column one of the brushes BCP is connected, by a plug connection 352, to the other coil of the same control relay 451. For column two, a second control relay 458 is plugged likewise. For the entry of invariable items, two elements of a counter 36| are each connected to a magnet 26|, by plug connections 353. The relay 425 for the resetting magnet is connected to contact C51 by a plug connection 354. The motor is started by closing switch 362. The perforated pattern cards hereinafter designated CM! CM2, which are to be duplicated, are stacked in hopper 34, Fig. 1, and blank cards hereinafter designated CVI, CV2 are stacked in hopper I5. The operator depresses the start key M, which closes the two contacts MI and M2 and establishes the following circuit: Line 336,

magnets

2 and 3, contacts Mi, 331, |33a, 333, 4266i, wire 333, contact M2, line 335.

Relays

2 and 3 are energized and close contacts 2a, b, c, and 3a. Relay 4 is energized by a circuit through contacts 2b, C5, and relay 5v is energized by a circuit through contacts 442D, 2c. The two

clutch magnets

68 and 81, Fig. 2 are energized by the circuits: Line 336, magnet 68, contact 2a. line 335 and line 336, magnet 81, contacts 4321), 2c, line 335. The two card feeding -devices are operated at the sa-me time and the pattern card CMI and the` blank card CVI are advanced as shown in graph Fig. 12.

The opera-tor releases the key and the machine stops when, at the end of the cycle, contacts C2 and C3 are opened, contacts |3f and 4231i being open. The operator depresses the key again until the cards have been so advanced that card contacts CC266 and C0342 are closed by the cards, which causes energization of relays I3 and 423 and subsequent closure of contacts |3f and 4231. Contacts 8e, |6f, 4|1f and 42H are closed by the energization of their corresponding magnets, owing to the closure oi card contacts C0294, 255 and 261 by the cards. Relay 6 is energized by the closure of contact CMM which is closed as long as there are cards in the pattern card hopper. Relay 4 5 is energized by the closure of contact CMP which is closed as long as there are cards in the blank card hopper, Fig. 15a.

The energization of

clutch magnets

68 and 81 is maintained by contacts 4b, 331, |38a, 338, 420a, 1b, 3e, |62, |3f, 4|5f, 4|1f, 42|f, 4231 and C6, and the machine runs automatically.

During the second cycle, the first pattern card passes brushes BSM while the 'blank car-d passes brushes BSP, as shown in Fig. 12. No analysis takes place.

During the third cycle, the first pattern card passes brushes BLM. The brushes make contact through the perforations and magnets 26| are energized 'by the following circuit: Line 335, impulse contact 343, contact C56, contact |0e, brush 345, contact roller 6|,` perforation, analyzing brush, plug connection 350, magnet 26|, line 336. The energization of a magnet 26| causes the corresponding punch to be locked as hereabove described.

' sponding to said numeral.

The entry of invariable items contained in counter 36| (see Fig. 15) is effected at the same time as the analysis of the pattern card. Contacts C343 and C45 are closed in synchronism with the passing of the perforations of the card in front of the analyzing brushes. If a counter element contains a numeral, the reading out device of the totalizer element establishes contact, in a manner well known in totalizers of this kind, -between the common strip 363 and a line 36d corre- When a contact C36 to C125 corresponding to said line is closed, an impulse, timed to correspond to the numeral, is emitted through the following circuit: Line 335, impulse contact 3dS, contact C56, one of the contacts C56 to C25, line 352, common strip 353, plug connection 353, magnet 26i, line 335. The first blank card is arrested at the end of the third cycle, just when it has reached its punching position beneath the punches, by the stopping of feed rollers 28, i129 due to the intermittent drive shown in Fig. 6 and hereabove described.

At the beginning of the fourth cycle, the die plate is moved upwards, and the rst blank card is punched according to the items contained in the data receiving device, that is, according to the first pattern card and to the invariable items transferred from the counter.

When the punching operation is finished, the die plate is moved downwards into its initial position and the card moved forwards again. At this moment, contact C57 establishes the following circuit: Line 335, lcontacts 343, C57, plug connection 351i, relay 25, line 336. Contacts 425er and b close and magnet 287 is energized by the circuit: Line contact C2 i, contacts Mrz, 2513, magnet 231', contact C55, line .336. When magnet 267 is energized, the data receiving device is reset to zero as hereabove described. The resetting to zero is effected just before the second pattern card is analyzed by brushes BLM. During the fourth cycle, the iirst pattern card and the first blank card now punched, are moved forwards, while data from the second pattern card are transferred to the data receiving device. At the end of the cycle, the second blank card is arrested beneath the punches.

During the fifth cycle, the first pattern card passes brushes BCM while the first blank card, now punched, passes brushes BCP. A control is then performed to ensure that the blank card has been perforated in absolute accordance with the pattern card.

1f for column one, for example, the two cards have perforations of the same value, owing to the analysis of the two cards by the rows of brushes BCM and BCP respectively, the two coils of relay d? connected to said column, receive impulses at the saine time; contacts 45M and @57h close while contacts ilc and lld open and no circuit is established for magnet i3?.

It is the same for the other control relays which have been plugged. In the case when, for any vcolumn which has been plugged, the perforations of the two cards are not the same, the two coils of the relay connected to said column are energized at different moments. ff, for example, only the left hand coil of relay i5? is energized, contact closes, whereas contact lilb remains open. A circuit is established as follows: Line 535, contacts della, tild, relay i3?, wire H35, line 335, Relay 37 is held by a circuit through C58, ific, lilith. Relay 33 is energized by the closure of contact ilb, and opens contact I38a in the circuit of clutch magnets 5t, Si. These magnets i2 are thus de-energized and the machine stops. ln the graph Fig. l2, the beginning and the end of the analysis for the control of the first pattern card and the rst blank card, are indicated by two horizontal lines CO and CF.

The machine continues to operate until all pattern cards have been duplicated, and the accuracy of the duplication has been determined.

(2) Punching of cards in sferica-The machine is plugged as shown to the right hand side of Fig. 15b, comprising brushes BSP, BCP.

A number of master cards one of which is designated Ai, Fig. 13, each followed by any desired number of blank cards CVI, CV2 are stacked in the blank card hopper i5, Fig. l, comprised in the card feeding device provided with a punching device P, and the machine is started as hereabove described. Switch 3535 at the lower right hand corner of Fig. 15b is closed. During the second cycle, the master card AI is analyzed by brushes BSP as shown in the left hand graph of Fig. 13. The master card is provided with a special perforation to distinguish it from other cards. It is assumed that this special perforation is a perforation ze in the eleventh index point position of column eighty. The corresponding one of the brushes BSP is connected by a plug connection 355 in series with a contact Cilwhich is. closed only when the perforation ="x passes the brushes. Through said contact the brush is connected to relay 42 by a plug connection 356, to relay 425 by a plug connection 351, and to relay 421 by a plug connection 358. These three relays are thus energized. The energization of relay 425 causes, as has been already described, the resetting to zero of the data receiving device after the punching of the last blank card of the preceding group, at the beginning of the third cycle. The energization of relay 5132, which is maintained by a circuit through contacts fiZa and C33, causes contact M217 to open in the circuit of clutch magnet 87, and thus, when C2 opens, relay 5 and magnet 81 are no longer energized. Through clutch 82, Fig. 2, the feed roller Il is disconnected from the drive and stopped, and the blank card which follows the master card is arrested during the third cycle. By the opening of C33, relay M2 is no longer maintained, and contact e421) closes, so that the advance of the blank card may be resumed at the beginning of the fourth cycle.

The energization of relay 421 is maintained by a circuit through contacts 421e, C22 and causes contact 4211) to close. Further, the energization of relay l2? causes the selecting contacts 443a, b, c, etc., to close during the fth cycle as hereinafter explained.

During the third cycle, the master card is moved forwards beneath the punches, while the following blank card is arrested. The data receiving device is reset to zero as has been described. At the beginning of the third cycle, Contact C23 establishes the circuit for relay 528, through contact 42717. Contact C22 opens, thereby causing relay 421 to be de-energized. Contact C59 establishes a holding circuit for relay 428, through vcontact 428e.

At the beginning of the fourth cycle, relay 429 is energized by a circuit through contacts C24, B281), and held by a circuit through contacts 429a, C50, whereas relay 428 is no longer energized. At the beginning of the fourth cycle, the punching operation has no effect and the master card is not punched as the data receiving device is empty. and no latch lever 244 is in latching posi-
